how to build my first wood longboard?

hey there everybody,
first of all, im new to the forum, and im new to surfing. strangely, im landlocked, but ive heard about river surfing near my home, and i wanted to give it a try. just a couple small issues, though: they dont sell surfboards here, and im on a very tight budget!
so.... i was wondering if someone could give me some advice on how to build my first longboard! i wanted to make it a solid wood longboard, maybe 8 or 9 ft long. u guys tell me which would be better! i was thinking making it 20 in. wide, and have 3 fins... i also dont know what kind of general shape a surfboard should have, or the essential parts of a surfboard, so could someone maybe please take the time to tell me what i need to do to my surfboard and how i should shape it so it is good (enough) and ride-able?
i was going to use 2 1inch thick 9 ft long 12 in wide pine boards to make the surfboard. i was gonna glue them together, then cut out the general shape, and from that i was going to file in all the details, and finish up the shaping... does my plan sound ok so far?
thanks a lot guys, sorry for the newB questions!
